Living cells have unique functions that can be harnessed by engineers to tackle human problems in energy, water, food, and health.
Historically living cells were considered too difficult to predictably engineer because of their complexity, vulnerability, and continuous change in state. The elucidation of the design principles that underlie cell function along with increasing numbers of examples of hybrid cell based devices are slowly erasing that notion.
In this class you will be learn about these established and emerging cellular design principles and begin to view cells as machines. This knowledge can also then be applied to non-living devices that mimic and communicate with cells. You will also be introduced to current and emerging living/non-living biohybrid devices such as biohybrid robots and neural implants.

Have you ever wondered why humans walk on two legs rather than four? In this course, we will explore how science investigates this unusual form of locomotion. We will start our investigation by looking at the mechanics of upright walking in humans and comparing that to bipedal locomotion in large birds, bears, and apes.
We will journey back millions of years into the human fossil record in an effort to understand how and why upright walking evolved. Around our first birthday, each of us learned how to walk, but how does this happen? With bipedalism came costly trade-offs as well-- we’ll examine these aches and pains as byproducts of our evolutionary history.
This course will take an intentionally interdisciplinary approach to studying how and why humans move bipedally. You will be exposed to anthropology, biomechanics, anatomy, evolution and paleontology to explore something deeply human: upright walking.
This course was developed in collaboration with SmithsonianX (National Musuem of Natural History and the National Zoological Park).
Birds are amazing animals! They are extremely intelligent, quite social, and some can make ideal companions! From parrots to parakeets, chickens to canaries and cockatoos, there are many species of birds to choose from when considering these feathered friends as pets.
This course provides introductory material about pet bird care including behavioral characteristics of different species of birds, bird handling, anatomy and physiology, and keeping birds as pets. Bird enthusiasts, pet bird owners, and others who work with birds will learn interesting and practical information!
In this course, we go beyond the calculus textbook, working with practitioners in social, life and physical sciences to understand how calculus and mathematical models play a role in their work.
Through a series of case studies, you’ll learn:
- How standardized test makers use functions to analyze the difficulty of test questions;
- How economists model interaction of price and demand using rates of change, in a historical case of subway ridership;
- How an x-ray is different from a CT-scan, and what this has to do with integrals;
- How biologists use differential equation models to predict when populations will experience dramatic changes, such as extinction or outbreaks;
- How the Lotka-Volterra predator-prey model was created to answer a biological puzzle;
- How statisticians use functions to model data, like income distributions, and how integrals measure chance;
- How Einstein’s Energy Equation, E=mc2 is an approximation to a more complicated equation.
With real practitioners as your guide, you’ll explore these situations in a hands-on way: looking at data and graphs, writing equations, doing calculus computations, and making educated guesses and predictions.
This course provides a unique supplement to a course in single-variable calculus. Key topics include application of derivatives, integrals and differential equations, mathematical models and parameters.
This course is for anyone who has completed or is currently taking a single-variable calculus course (differential and integral), at the high school (AP or IB) or college/university level. You will need to be familiar with the basics of derivatives, integrals, and differential equations, as well as functions involving polynomials, exponentials, and logarithms.
This is a course to learn applications of calculus to other fields, and NOT a course to learn the basics of calculus. Whether you’re a student who has just finished an introductory Calculus course or a teacher looking for more authentic examples for your classroom, there is something for you to learn here, and we hope you’ll join us!
